Answer 1

The correct option is C $40$ metres

See the image.

Mohit starts walking from point 'A' walks up to point B at $20$ m. From there he took left turn and walked $10$ m then he took right turn and walked $10$ m and reached point 'E'.

E is in line with A and at a distance of $20+20$ = $40$ m from A.
